Sub-Mariner #29

The Huntsman of Zeus uses sirens (green skinned women who play lyres) to hypnotize the Sub-Mariner to attack Hercules. After Namor battles Hercules on a small Mediterranean island, he is eventually freed of his hypnotism and teams up with Hercules to defeat three giants brought forth by the Huntsman; Polyphemus (a giant cyclops with a jewel for an eye), Scylla (a huge stoneman), and Charybdis (a huge bipedal dragon). Namor and Hercules defeat the monsters and the Huntsman. Hercules returns to Olympus while Zeus erases Namor's memory of the battle.
